through the front end of the box F, and has a wheel G, upon it into whicha wheel H, on a shaft I, gears. The frontend of the screw shaft c, has its bearing in `the same block d, as the lower end ofthe shaft B, and

the two shafts B, c, are connected by bevel gears f, f, as shown in Fig. l. `The lower part of thecylinder A, communicates with v the boxor receiver F, by meanslof a sprout J.

(K, is a shaft which is placed just beyond the back of the boX or receiver F, and` has a wheel L, upon it, the back part of which works in the end ofthe box or receiver F,

"This wheel L, has its peripheryperforated with oblong rectangular openings g, which i form the brick molds and in eaclimold g, there is placed a piston or plunger it, the area of which corresponds to that of the molds. l The pistons are each provided with a rod or stem i, and their rods or stems project through' a sole or circular plate y,

which forms the inner periphery of the s "wheel L, as shown inFigs. l and 3. The Y rods or stems z', are each provided with a The `wheel L, is permanently attached to its shaft K, and on this shaftthere is placed abevel wheel M, into which abevel pinion N, on the shaft I, gears as shown in Fig. 2.

- To one side of the wheel L, there is attached concentrically a toothed rim O, the teeth being at the inner edge of the rim and having a pinionP, gearing into vthem` which works on `a small shaft 7c, that enters wheel L. The pinion'P, has a cylinder Q, attached to its inner end, the periphery" of which is` corrugatedas shown in Figs. 1 and 3."

T, is a box which is fitted transversely in the lower part of the box or receiver F, and just back ofthe wheel L, as shown in Fig; l, and the lower front end ofthe boX or receiver F, is made of V form-as shown at a',

to'serve as a scraper and take the superfluous'clay from the periphery ofthe wheel L, and also to smooth and compact the clay at the surfaces of the molds g. `The boX or slide T, receives stones orfotherhard foreign substances in the clay which cannot be em-l bedded in the molds and consequently project out from their orices. This box T, may be removed at pleasure for the purpose of being emptied of its contents. a

\ The operation is 'as follows: The clay to bemolded and pressed is thrown in a properly moistened state into the upper end of the hollow cylinder A, and the shaft B, is

rotated by any convenient power. The clay `Whcn the clay reaches the bottom of cylin' der A, it is properly ground and tempered and is forced through the spout J, into the box or receiver F. The screw G, which is rotated from the shaft B, by means f the bevel gears f, f, forces the clay Within the box or receiver F, to the Wheel L, and into the molds g, thereof said Wheel rotating in the direction indicated by the arrow l. The screw Gr, compacts the clay firmly in the molds g, forcing the pistons or plungers ii, back to the inner ends of the molds. The filled molds as the Wheel L, rotates of course pass out from underneath the end of the box or receiver F, and so the inner ends of the rods or stems z', come in contact with the cylinder Q, the plungers L, are forced down and the molded clay ejected from the molds. rlhe cylinder Q, it Will be see-n is rotated in consequence of the pinion P Which is attached to it gearing into the toothed rim O. The molded clay may be discharged upon an endless apron or any suitable carrier to convey them from underneath the wheel L. The Wheel L is rotated from shaft I, through the medium of the gearing M N.

Thus it will be seen that all the Working parts of the machine have a continuous rotary motion and consequently Will Work smoothly and Well without the liability of getting out of repair.

I do not claim broadly and separately a rotating mold-wheel provided with plungers for that has been previously used, nor do I claim a mold or clay-tempering mill, separately or in itself considered, but

Having thus described my invention what claim as new and desire to secure by Letters Patent isl. The rotating clay-grinding or tempering device formed of the knives D, and spiral ilanches C, shaft B, and the stationary knives E, in cylinder A, in combination with the feeding screw G in the box or receiver F and the rotary mold-Wheel L provided With the plungers It, substantially as and for the purpose herein set forth.

2. The box T, placed transversely in the loivei' part of the box or receiver F and in such relation with the mold-Wheel L and projection 0; to operate as and for the pun pose specified.
